Bone marrow harvest is a surgical procedure to collect bone marrow — the spongy tissue inside your bones that makes blood cells. The marrow is taken from the back of your pelvic bone using a needle, while you are under anesthesia (medicine to make you sleep and feel no pain). This marrow is then given to someone who needs it for a transplant, often to treat blood cancers or other blood disorders.
Key facts
Bone marrow harvest is not an everyday procedure, but it is performed regularly at specialized hospitals. Thousands of bone marrow transplants happen each year worldwide.
Bone marrow harvest is done on healthy donors (often family members or volunteers) who are a good match for a patient needing a transplant. It may also be done on patients themselves if their own marrow is healthy enough to be collected and given back after high-dose treatment.
A bone marrow harvest is not diagnosed — it is a treatment procedure. The decision to harvest bone marrow is based on the recipient's diagnosis, which is made through blood tests, bone marrow biopsies, and imaging.
If you are a donor, you will have a health screening that includes blood tests and a physical exam to ensure you are fit for the procedure. The harvest itself is done under anesthesia, so you will not be awake. Afterward, you may stay in recovery for a few hours before going home.
A bone marrow harvest is part of a bone marrow transplant treatment for the recipient. Before the transplant, the recipient often receives chemotherapy and/or radiation to destroy diseased marrow. Then the harvested marrow is infused into their bloodstream, where it can travel to the bones and start making healthy blood cells.
Medical care for the recipient includes a period of isolation to prevent infection while the new marrow grows. Medicines to prevent rejection and treat complications are given, but specific names and doses are determined by the healthcare team.
Bone marrow harvest itself is a surgical procedure. It is usually done as a standalone surgery but may be part of a larger treatment plan for the recipient.
For donors, recovery is quick — most people return to normal activities within a few days to a week. You may feel tired for a short time, but your body replaces the donated marrow within a few weeks.
Eat a healthy, balanced diet and drink plenty of water. Gentle walking is fine, but wait a week before heavy lifting or intense exercise.
Donating bone marrow can be a positive experience, but some donors may feel anxious or emotional. It is normal to have mixed feelings. Talk to your healthcare team if you need support.
There is no way to prevent the need for a bone marrow harvest because it is a treatment for diseases that are not preventable. Maintaining a healthy lifestyle may reduce the risk of some conditions, but it cannot guarantee prevention.
Most bone marrow donors recover fully with no long-term problems. For recipients, a bone marrow transplant can be life-saving, but success depends on many factors. Many people go on to live healthy lives after transplant.
